Python 面向对象 例子

class Employee:
    empCount = 0
    def __init__(self, name, salary):
           self.name = name
           self.salary = salary
        Employee.empCount +=1
       def displayCount(self):
             print "Total Employee %d" % Employee.empCount
       def displayEmployee(self):
              print "Name : ", self.name,  ", Salary: ", self.salary

t=Employee("Candy","10000000$")
t.displayCount()
t.displayEmployee()

 

类方法通过类实例调用，类变量通过类名调用。

emp1.displayEmployee()
emp2.displayEmployee()
print "Total Employee %d" % Employee.empCount
